An operations team manages Linux servers over SSH. The security team wants to stop direct management access from employee laptops, reduce lateral movement if one admin endpoint is compromised, and keep a log of every administrative session. Which two design choices best fit? Select two.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Best answer
Require administrators to connect to a bastion host or jump server before reaching the Linux servers.
A bastion host is a hardened choke point for privileged access, so all administrative sessions can be concentrated, filtered, and monitored. It prevents direct SSH exposure from general user systems and gives the security team a single place to enforce logging and session control. This is a common hardened management-path pattern.
Distractor review
Let all corporate laptops connect directly to SSH on the servers if MFA is enabled.
MFA is useful, but direct access from every corporate laptop still expands the attack surface and makes lateral movement much easier after an endpoint compromise. The scenario explicitly asks to stop direct management access and reduce spread, so a central jump path is better than broad direct reachability.
Best answer
Restrict management interfaces so only the bastion host can reach them and log each session.
Limiting server management interfaces to the bastion host creates a strong network boundary and prevents administrators from bypassing the controlled access path. Session logging provides traceability and supports investigations and accountability. This complements the bastion by ensuring the network architecture enforces the same control model.
Distractor review
Expose SSH to the internet because key-based authentication is already strong.
Publicly exposing SSH is unnecessary and increases brute-force, scanning, and exploitation risk. Key-based authentication helps, but it does not justify direct internet access to management services. The requirement is to remove direct access from employee laptops, not extend management services to untrusted networks.
Distractor review
Use split tunneling for admin traffic so management packets can bypass the VPN.
Split tunneling is generally used to route some traffic outside the secure tunnel, which is the opposite of what this scenario needs. Management traffic should be tightly controlled and inspected, not routed around security controls. Bypassing the VPN would weaken the protected management path.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Require administrators to connect to a bastion host or jump server before reaching the Linux servers. — The best architecture uses a bastion host as the only entry point for administration and limits the managed servers so only that host can reach their management interfaces. This design sharply reduces direct exposure, creates a centralized audit trail, and helps contain compromise if an admin workstation is attacked. It is a secure, practical way to support SSH administration. Why others are wrong: Direct SSH from all corporate laptops leaves the servers reachable from many endpoints and increases lateral movement risk. Exposing SSH to the internet is even worse because it broadens the attack surface unnecessarily. Split tunneling would allow management traffic to avoid the controlled path, undermining the central logging and access restrictions the scenario requires.
